Friends of Cancer Research Annual meeting November 16, 2016
What is RWD/RWE? Real World Data (RWD) Electronic Health Record (EHR) clinical data Patient registries Surveys Pragmatic trials Administrative claims/billing Mobile health (smartphones, wearables, social media) Real World Evidence (RWE) Data generated for purposes other than evidencegeneration from a traditional clinical trial 6
Why RWE/RWD? U.S. adult cancer clinical trials relatively homogenous, expensive, (s)low accrual, administrative burdens Questions regarding generalizability once the drug enters the clinic New technologies may enable the collection and curation of diverse pipelines of data to enhance learning lifecycle of a therapy 7
Potential uses for RWD/RWE in oncology Labeling expansion for efficacy (rare tumor types) Real world dosage and administration Post-marketing safety Assessment of REMS Use in patients excluded from pivotal trials (e.g. autoimmune disease with immune checkpoint inhibitors) Assessment of special populations (hepatic/renal impairment, brain mets, leptomeningeal mets, elderly) Patient-reported toxicity/efficacy/function Prognosis in rare genomic subtypes Biomarker prediction (e.g. ORR and DoR based on liquid biopsy results versus tissue) Drug utilization www.fda.gov 8
Potential issues Missing data Data curation (structured vs unstructured) Cohort selection Informed Consent/ HIPAA Quality Assurance 9
Potential Use-Cases discussed in WG Observational post-marketing data in rare cancers Observational follow up of post-progression cross-over cohort in a randomized controlled trial Pragmatic randomized controlled trial exploring 2 different dosing strategies 10

RWE to Support Regulatory Decisions Use cases and considerations Michael D. Taylor, PharmD, PhD Deputy Global Head of Oncology Real World Data Science Genentech, A Member of the Roche Group
RWE for Regulatory Decisions What? Safety & Effectiveness PMC & Label expansion Why? Opportunity to learn Expedite clinical development for serious and life-threatening disease RCT feasibility and appropriateness
RWE Use Cases Prospectively designed observational study Randomized Phase 2 plus observational study Pragmatic trial
Observational Study Prospectively designed Phase 1b: Treatment A Early outcomes Long-term outcomes Time Observational Study: 1) Treatment A & 2) SOC Early outcomes Long-term outcomes
Observational Study Prospectively designed Considerations Study outcomes Selection bias and confounding Patient identification Sample size
Randomized Phase 2 Study Plus observational study Treatment A Early outcomes Long-term outcomes R Physician s Choice or SOC Treatment A Obs Physician s Choice or SOC
Randomized Phase 2 Study Plus observational study Study Design & Methodological Issues Trial setting vs observational setting Sample size Potential for accelerated approval on randomized Ph2 and conversion with long term observational data
Pragmatic Trial Explore new dose Study data source: Electronic Health Records Early outcomes Long-term outcomes R Treatment A Approved dose Treatment A Alternate dose
Pragmatic trial Study Design & Methodological Issues Randomization Consent
Considerations Data Quality Operational & Logistical Issues Patient level data submission Auditing of source data HIPPA Data standardization across EMR systems Linkage of EMR and claims Consent
Final Thoughts Opportunity to learn through pilots and dialogue Test ability of data to answer key questions Test feasibility can we identify and overcome operational/logistical challenges? Opportunity to help patients while learning

Observational data to complement trials Case 1: Use of observational data to examine effectiveness of approved agents used in the off-label setting 2016 Flatiron Health, Inc. Proprietary and confidential. 28
RWE Potential Application: Observational data for off-label use of approved agents Context BRAF V600 inhibitors are approved in melanoma Data from Phase II basket trial in non-melanoma cancers had a signal of response in non-small cell lung cancer (N=20) Among people with BRAF+ non-small cell lung cancer, is there differential improved response when a BRAF inhibitor is administered? Because of the difficulty of conducting clinical trials in small population, real-world evidence could potentially supplement the clinical trial data RWE Application RWE database of >25,000 ansclc patients allows for identification and investigation of any patient cases with a BRAF V600 mutation, tested as part of routine clinical care Centralized, technology-enabled processing allows for further systematic assessment of outcomes by capturing real-world tumor endpoints, based on standardized methodology 2016 Flatiron Health, Inc. Proprietary and confidential. 29
RWE Potential Application: Observational data for off-label use of approved agents Potential selection diagram for BRAF+ patients in the ansclc RWE database, based on current cohort: Confirmed Advanced NSCLC N = 27,729 History of NGS testing Structured order for a BRAF inhibitor Free-text search for BRAF mutation BRAF V600E mutated Treated with a BRAF inhibitor Not treated with a BRAF inhibitor 2016 Flatiron Health, Inc.

Real-world follow up Case 2: Tracking utilization, effectiveness and safety in the transition from clinical trials to real-world care after regulatory approval 2016 Flatiron Health, Inc. Proprietary and confidential. 31
RWE Case Study: Tracking outcomes in the transition from clinical trials to real-world care Context FDA/Flatiron collaborative project to understand safety and outcomes for immune checkpoint inhibitors in ansclc as these treatments are adopted post-approval RWE Application Because patients continue to receive care, EHR platform and data processing supports longitudinal tracking Allows for updating the story with additional information on longer term outcomes - such as time on therapy, safety events and overall survival Next Steps All cases in Flatiron national dataset through March 31, 2016 Additional phases planned for further investigation based on preliminary findings 2016 Flatiron Health, Inc.
